CONVEYER 5 Sheets-Sheet 5 Filed June 11. 1937 The upper ends of hangers 3| are pivoted to the rear portions of the forward rocker arms 28, the lower ends of the hangers being pivoted to the end portions of the cross beam 3 of the first conveyer 2-3-4. Hangers 32 are disposed in advance of the hangers 3|, the upper ends of the hangers 32 being pivoted to the forward parts of the forward rocker arms 28, and the lower ends of the hangers 32 being pivoted to the ends of the cross beam 1 of the second conveyer 6-1-8.

Radius arms 33, of considerable length, have their rear ends pivoted to the ends of the cross beam 1 of the second conveyer 6-1-8. forward ends of the radius arms 33 are pivotally mounted at 34 on the side walls of the casing I. The radius rods 33 have small inclination with respect to the horizontal, the radius rods 33 are of considerable length, and, consequently, asthe rear ends of the radius, rods, together with the beam 1 of the second conveyer 6-1-8 move up and down, the horizontal component in that movement is inappreciable. Y

The drive is initiated at the means 12, which imparts rotation to the drive shaft 1 I. From the drive shaft II, rotation is imparted to the driven shaft I4 by the intermeshing gears 15. From the shaft 14, rotation is imparted to the operating shaft 16 by the chain andsprocket drive 11. The crank disks I8 on the ends of the shaft 16 operate the pitmans l9, and the pitmans impart a horizontal component to the movement to the first conveyer 2-3-4.

The shaft I4, the crank disks 24, the connecting rods 23,, the rear rocker arms 2| and the hangers 26 give a vertical component to the movement of the first conveyer 2-3-4, and the hangers 21 give a vertical component to the movement of the second conveyer fi-l-8. From the rear rocker arms 2 I motion is transmitted to the forward rocker arms 28 by way of the links 33, The forward rocker arms 28 swing on their pivotal mountings 29, the hangers raise and lower the first conveyer 2-3-4, and the hangers 32 raise and lower the second conveyer 6-1-8. It is to be. observed that the second conveyer 6-1-8 has practically no horizontal movement, owing to the provision of the radius rods 33. The first conveyer 2-3-4, however, is not restrained by any structurecorresponding 'to the radius rods 33, and has in its movement a horizontal component due to the throw of the crank disks 18 on the shaft l6. Practically speaking, the second conveyer 6-1-8 moves up and down only, where- The as the first conveyer 2-3-6 has an elliptical or orbital movement in a clockwise direction.

In order that such words as forward, rear, backwardly, and the like, in the following paragraph, may be understood clearly, it will be well to note again at this point, by reference to Fig. 1, that the arrow A designateswhat is called the forward end of the machine, the rear end of the machine being designated by the arrow B.

Recalling that the second conveyer 6-1-8, represented by the teeth 9 in Figs. 6 to 10, has, in substance, avertical movement only, due to the provision of the radius rods 33 of Fig. 1,

whereas the first conveyer 2-3-4, represented by the teeth 5 in Figs. 6 to 10, has a clockwise elliptical orbital movement, including both horizontal and vertical components, the fruit introduced at the forward end of the machine may be regarded as being lodged between the teeth 9 of the second conveyer 6-1-8, as shown at 35 in Fig. 6. Then the fruit is eased down along the rear edges of the teeth 5 of the first conveyer 2-3-4 as indicated at 36 in Fig. 7, lodged in the angles between the teeth 5, as shown at 31 in Fig. 8 and passed over the teeth 9 of the conveyer 6-1-8, lodged between the teeth 9 and moved upwardly along the forward edges of the teeth 5, as-indicated at 38 in Fig. 9, and finally carried over the teeth 5, as at 39 in Fig. 10, the cyclebeing repeated until the fruit passes out of rear end of the machine.

It will be noted that, although the fruit is rolled through the machine, there is no bumping of the fruit, the combined rolling and advancing movement of the fruit taking place as a gentle, advancing progression.

Having thus described the invention, what is claimed is:

In a device of the class described, a casing, first and second conveyers disposed side by side in the casing and having upstanding teeth, duplicate mechanisms connected to the conveyers for imparting up and down movement thereto in parallel planes, radius arms pivoted to the second conveyer and to the casing and constituting means for constraining the second conveyer against horizontal right line reciprocation, means cooperating with one of said mechanisms for imparting elliptical movement to the first conveyer, an operating connection between said mechanisms, and driving means connected to one of said mechanisms.
